AMIDE COMPOUNDS AND METHOD FOR MAKING AND USING

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of the earlier filing date of U.S. provisional patent application No. 62/413,299, filed October 26, 2016, which is incorporated herein by reference in its entirety.

FIELD

This disclosure concerns amide compounds, and embodiments of a method for making and using the compounds, such as for inhibiting interleukin receptor-associated kinase (IRAK), and for treating diseases and conditions related to IRAK.

BACKGROUND

Interleukin-1 receptor-associated kinases (IRAKs) are important mediators of signaling processes, such as toll-like receptors (TLR) and interleukin-1 receptor (IL-IR) signaling processes. IRAKs have been implicated in modulating signaling networks that control inflammation, apoptosis, and cellular

differentiation. Four IRAK genes have been identified in the human genome (IRAKI, IRAK2, IRAK3 and IRAK4), and studies have revealed distinct, non-redundant biological roles. IRAKI and IRAK4 have been shown to exhibit kinase activity.

DETAILED DESCRIPTION

I. Definitions

The following explanations of terms and methods are provided to better describe the present disclosure and to guide those of ordinary skill in the art in the practice of the present disclosure. The singular forms "a," "an," and "the" refer to one or more than one, unless the context clearly dictates otherwise. The term "or" refers to a single element of stated alternative elements or a combination of two or more elements, unless the context clearly indicates otherwise. As used herein, "comprises" means "includes." Thus, "comprising A or B," means "including A, B, or A and B," without excluding additional elements. All references, including patents and patent applications cited herein, are incorporated by reference.

Unless otherwise indicated, all numbers expressing quantities of components, molecular weights, percentages, temperatures, times, and so forth, as used in the specification or claims are to be understood as being modified by the term "about." Accordingly, unless otherwise indicated, implicitly or explicitly, the numerical parameters set forth are approximations that may depend on the desired properties sought and/or limits of detection under standard test conditions/methods. When directly and explicitly distinguishing embodiments from discussed prior art, the embodiment numbers are not approximates unless the word "about" is expressly recited.

Unless explained otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure pertains. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present disclosure, suitable methods and materials are described below. The materials, methods, and examples are illustrative only and not intended to be limiting.

When chemical structures are depicted or described, unless explicitly stated otherwise, all carbons are assumed to include hydrogen so that each carbon conforms to a valence of four. For example, in the structure on the left-hand side of the schematic below there are nine hydrogen atoms implied. The nine hydrogen atoms are depicted in the right-hand structure.

Sometimes a particular atom in a structure is described in textual formula as having a hydrogen or hydrogen atoms, for example -CH ₂ CH ₂ -. It will be understood by a person of ordinary skill in the art that the aforementioned descriptive techniques are common in the chemical arts to provide brevity and simplicity to description of organic structures.

If a group R is depicted as "floating" on a ring system, as for example in the group:

then, unless otherwise defined, a substituent R can reside on any atom of the fused bicyclic ring system, excluding the atom carrying the bond with the " >~w " symbol, so long as a stable structure is formed. In the example depicted, the R group can reside on an atom in either the 5-membered or the 6-membered ring of the indolyl ring system.

When there are more than one such depicted "floating" groups, as for example in the formulae:

where there are two groups, namely, the R and the bond indicating attachment to a parent structure; then, unless otherwise defined, the "floating" groups can reside on any atoms of the ring system, again assuming each replaces a depicted, implied, or expressly defined hydrogen on the ring system and a chemically stable compound would be formed by such an arrangement.

When a group R is depicted as existing on a ring system containing saturated carbons, as for example in the formula:

where, in this example, y can be more than one, assuming each replaces a currently depicted, implied, or expressly defined hydrogen on the ring; then, unless otherwise defined, two R's can reside on the same carbon. A simple example is when R is a methyl group. The depicted structure can exist as a geminal dimethyl on a carbon of the depicted ring (an "annular" carbon). In another example, two R's on the same carbon, including that same carbon, can form a ring, thus creating a spirocyclic ring (a "spirocyclyl" group) structure. For example, shown below two Rs can form a piperidine ring in a spirocyclic arrangement with the cyclohexane, as

As used herein, the term "substituted" refers to all subsequent modifiers in a term, for example in the term "substituted arylCi-salkyl," substitution may occur on the "Ci-salkyl" portion, the "aryl" portion or both portions of the arylCi-salkyl group.

"Substituted," when used to modify a specified group or moiety, means that at least one, and perhaps two or more, hydrogen atoms of the specified group or moiety is independently replaced with the same or different substituent groups as defined below. In a particular embodiment, a group, moiety or substituent may be substituted or unsubstituted, unless expressly defined as either "unsubstituted" or "substituted." Accordingly, any of the groups specified herein may be unsubstituted or substituted. In particular embodiments, the substituent may or may not be expressly defined as substituted, but is still contemplated to be optionally substituted. For example, an "alkyl" or a "pyrazolyl" moiety may be unsubstituted or substituted, but an "unsubstituted alkyl" or an "unsubstituted pyrazolyl" is not substituted.

In one embodiment, a group that is substituted has at least one substituent up to the number of substituents possible for a particular moiety, such as 1 substituent, 2 substituents, 3 substituents, or 4 substituents.

Additionally, in embodiments where a group or moiety is substituted with a substituted substituent, the nesting of such substituted substituents is limited to three, thereby preventing the formation of polymers.

Thus, in a group or moiety comprising a first group that is a substituent on a second group that is itself a substituent on a third group, which is attached to the parent structure, the first (outermost) group can only be substituted with unsubstituted substituents. For example, in a group comprising -(aryl-l)-(aryl-2)-(aryl-3), aryl-3 can only be substituted with substituents that are not themselves substituted.

Any group or moiety defined herein can be connected to any other portion of a disclosed structure, such as a parent or core structure, as would be understood by a person of ordinary skill in the art, such as by considering valence rules, comparison to exemplary species, and/or considering functionality, unless the connectivity of the group or moiety to the other portion of the structure is expressly stated, or is implied by context.

"Acyl" refers to the group -C(0)R, where R is H, aliphatic, hetero aliphatic, heterocyclic or aromatic.

An aliphatic group may be substituted or unsubstituted, unless expressly referred to as an "unsubstituted aliphatic" or a "substituted aliphatic." An aliphatic group can be substituted with one or more substituents (up to two substituents for each methylene carbon in an aliphatic chain, or up to one substituent for each carbon of a -C=C- double bond in an aliphatic chain, or up to one substituent for a carbon of a terminal methine group).

"Alkoxyalkyl" refers to the group -alkyl-OR, where R is a substituted or unsubstituted alkyl or a substituted or unsubstituted cycloalkyl group.

"Alkyl" refers to a saturated aliphatic hydrocarbyl group having from 1 to 25 (Ο-25) carbon atoms, typically 1 to 10 (CMO) carbon atoms such as 1 to 6 (Ci-β) carbon atoms. An alkyl moiety may be substituted or unsubstituted. This term includes, by way of example, linear and branched hydrocarbyl groups such as methyl (CH ₃ ), ethyl (-CH2CH3), n-propyl (-CH ₂ CH ₂ CH ₃ ), isopropyl (-CH(CH ₃ ) ₂ ), n-butyl (-CH ₂ - CH2CH2CH3), isobutyl (-CH ₂ CH ₂ (CH ₃ )2), sec-butyl (-CH(CH ₃ )(CH ₂ CH ₃ ), t-butyl (-C(CH ₃ ) ₃ ), n-pentyl (- CH2CH2CH2CH2CH3), and neopentyl (-CH ₂ C(CH ₃ ) ₃ ).

"Amino" refers to the group -N¾, -NHR, or -NRR, where each R independently is selected from H, aliphatic, heteroaliphatic, aromatic, including both aryl and heteroaryl, or heterocycloaliphatic, or two R groups together with the nitrogen attached thereto form a heterocyclic ring. Examples of such heterocyclic rings include those wherein two R groups together with the nitrogen to which they are attached form a - (CI¾)2-5- ring optionally interrupted by one or two heteroatom groups, such as -O- or -N(R ^g ) such as in the groups wherein R ^g is R , -C(0)R ⁷⁰ , -C(0)OR ⁶⁰ or -C(O)N(R ⁸⁰ ) ₂ .

"Amide" or "carboxamide" refers to the group -N(R)acyl, or -C(0)amino, where R is hydrogen, hetero aliphatic or aliphatic, such as alkyl, particularly Ci-6alkyl.

"Treating" or "treatment" as used herein concerns treatment of a disease or condition of interest in a patient or subject, particularly a human having the disease or condition of interest, and includes by way of example, and without limitation:

(i) preventing the disease or condition from occurring in a patient or subject, in particular, when such patient or subject is predisposed to the condition but has not yet been diagnosed as having it;

(ii) inhibiting the disease or condition, for example, arresting or slowing its development; (iii) relieving the disease or condition, for example, causing regression of the disease or condition or a symptom thereof; or

(iv) stabilizing the disease or condition.

As used herein, the terms "disease" and "condition" can be used interchangeably or can be different in that the particular malady or condition may not have a known causative agent (so that etiology has not yet been determined) and it is therefore not yet recognized as a disease but only as an undesirable condition or syndrome, where a more or less specific set of symptoms have been identified by clinicians. The above definitions and the following general formulas are not intended to include impermissible substitution patterns (e.g., methyl substituted with 5 fluoro groups). Such impermissible substitution patterns are easily recognized by a person having ordinary skill in the art.

Any of the groups referred to herein may be optionally substituted by at least one, possibly two or more, substituents as defined herein. That is, a substituted group has at least one, possible two or more, substitutable hydrogens replaced by a substituent or substituents as defined herein, unless the context indicates otherwise or a particular structural formula precludes substitution.

A person of ordinary skill in the art will appreciate that compounds may exhibit the phenomena of tautomerism, conformational isomerism, geometric isomerism, and/or optical isomerism. For example, certain disclosed compounds can include one or more chiral centers and/or double bonds and as a consequence can exist as stereoisomers, such as double -bond isomers (i.e., geometric isomers), enantiomers, diasteromers, and mixtures thereof, such as racemic mixtures. As another example, certain disclosed compounds can exist in several tautomeric forms, including the enol form, the keto form, and mixtures thereof. As the various compound names, formulae and compound drawings within the specification and claims can represent only one of the possible tautomeric, conformational isomeric, optical isomeric, or geometric isomeric forms, a person of ordinary skill in the art will appreciate that the disclosed compounds encompass any tautomeric, conformational isomeric, optical isomeric, and/or geometric isomeric forms of the compounds described herein, as well as mixtures of these various different isomeric forms. In cases of limited rotation, e.g. around the amide bond or between two directly attached rings such as the pyrazolyl and pyridinyl rings, atropisomers are also possible and are also specifically included in the compounds of the invention.

In any embodiments, any or all hydrogens present in the compound, or in a particular group or moiety within the compound, may be replaced by a deuterium or a tritium. Thus, a recitation of alkyl includes deuterated alkyl, where from one to the maximum number of hydrogens present may be replaced by deuterium. For example, ethyl may be C2H ₅ or C2H ₅ where from 1 to 5 hydrogens are replaced by deuterium, such as in C2D _X H5- _X .

As another example, rheumatoid arthritis (RA) typically results in swelling, pain, loss of motion and tenderness of target joints throughout the body. RA is characterized by chronically inflamed synovium that is densely crowded with lymphocytes. The synovial membrane, which is typically one cell layer thick, becomes intensely cellular and assumes a form similar to lymphoid tissue, including dendritic cells, T-, B- and NK cells, macrophages and clusters of plasma cells. This process, as well as a plethora of

immunopathological mechanisms including the formation of antigen-immunoglobulin complexes, eventually result in destruction of the integrity of the joint, resulting in deformity, permanent loss of function and/or bone erosion at or near the joint. The amide compound, combinations of amide compounds, or compositions thereof, may be used to treat, ameliorate or prevent any one, several or all of these symptoms of RA. Thus, in the context of RA, the compounds are considered to provide therapeutic benefit when a reduction or amelioration of any of the symptoms commonly associated with RA is achieved, regardless of whether the treatment results in a concomitant treatment of the underlying RA and/or a reduction in the amount of circulating rheumatoid factor ("RF").

The American College of Rheumatology (ACR) has developed criteria for defining improvement and clinical remission in RA. Once such parameter, the ACR20 (ACR criteria for 20% clinical improvement), requires a 20% improvement in the tender and swollen joint count, as well as a 20% improvement in 3 of the following 5 parameters: patient's global assessment, physician's global assessment, patient's assessment of pain, degree of disability, and level of acute phase reactant. These criteria have been expanded for 50% and 70% improvement in ACR50 and ACR70, respectively. Other criteria include Paulu's criteria and radiographic progression (e.g. Sharp score).

In some embodiments, therapeutic benefit in patients suffering from RA is achieved when the patient exhibits an ACR20. In specific embodiments, ACR improvements of ACRC50 or even ACR70 may be achieved. B. Formulations and Administration

The tablets may be coated by methods well known in the art with, for example, sugars, films or enteric coatings. Liquid preparations for oral administration may take the form of, for example, elixirs, solutions, syrups or suspensions, or they may be presented as a dry product for constitution with water or other suitable vehicle before use. Such liquid preparations may be prepared by conventional means with pharmaceutically acceptable additives such as: suspending agents (e.g., sorbitol syrup, cellulose derivatives or hydrogenated edible fats); emulsifying agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g., almond oil, oily esters, ethyl alcohol, cremophore™ or fractionated vegetable oils); and preservatives (e.g., methyl or propyl-p- hydroxybenzoates or sorbic acid). The preparations may also contain buffer salts, preservatives, flavoring, coloring and sweetening agents as appropriate.

Preparations for oral administration may be suitably formulated to give controlled release of the active compound or prodrug, as is well known.

For buccal administration, the compositions may take the form of tablets or lozenges formulated in conventional manner.

For rectal and vaginal routes of administration, the active compound(s) may be formulated as solutions (for retention enemas) suppositories or ointments containing conventional suppository bases, such as cocoa butter or other glycerides.

For nasal administration or administration by inhalation or insufflation, the active compound(s), hydrate, solvate, N-oxide, pharmaceutically acceptable salt or prodrug(s) can be conveniently delivered in the form of an aerosol spray from pressurized packs or a nebulizer with the use of a suitable propellant, e.g.,) dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, fluorocarbons, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges for use in an inhaler or insufflator (for example capsules and cartridges comprised of gelatin) may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.

A specific example of an aqueous suspension formulation suitable for nasal administration using commercially-available nasal spray devices includes the following ingredients: active compound or prodrug

(0.5 20 mg/ml); benzalkonium chloride (0.1 0.2 mg/mL); polysorbate 80 (TWEEN ^® 80; 0.5 5 mg/ml); carboxymethylcellulose sodium or microcrystalline cellulose (1 15 mg/ml); phenylethanol (1 4 mg/ml); and dextrose (20 50 mg/ml). The pH of the final suspension can be adjusted to range from about pH 5 to pH 7, with a pH of about pH 5.5 being typical.

Another specific example of an aqueous suspension suitable for administration of the compounds via inhalation contains 20 mg/mL of the amide compound(s) or prodrug(s), 1% (v/v) polysorbate 80

(TWEEN ^® 80), 50 mM citrate and/or 0.9% sodium chloride.

Therapeutic benefit means eradication or amelioration of the underlying disorder being treated and/or eradication or amelioration of one or more of the symptoms associated with the underlying disorder such that the patient reports an improvement in feeling or condition, notwithstanding that the patient may still be afflicted with the underlying disorder. For example, administration of a compound to a patient suffering from an allergy provides therapeutic benefit not only when the underlying allergic response is eradicated or ameliorated, but also when the patient reports a decrease in the severity or duration of the symptoms associated with the allergy following exposure to the allergen. As another example, therapeutic benefit in the context of asthma includes an improvement in respiration following the onset of an asthmatic attack or a reduction in the frequency or severity of asthmatic episodes. Therapeutic benefit also includes halting or slowing the progression of the disease, regardless of whether improvement is realized.

As known by those of ordinary skill in the art, the preferred dosage of amide compounds may depend on various factors, including the age, weight, general health, and severity of the condition of the patient or subject being treated. Dosage also may need to be tailored to the sex of the individual and/or the lung capacity of the individual, when administered by inhalation. Dosage may also be tailored to individuals suffering from more than one condition or those individuals who have additional conditions that affect lung capacity and the ability to breathe normally, for example, emphysema, bronchitis, pneumonia, and respiratory infections. Dosage, and frequency of administration of the amide compound(s) or compositions thereof, will also depend on whether the amide compound(s) are formulated for treatment of acute episodes of a condition or for the prophylactic treatment of a disorder. A person or ordinary skill in the art will be able to determine the optimal dose for a particular individual.

For prophylactic administration, the amide compound, combinations of amide compounds, or compositions thereof, can be administered to a patient or subject at risk of developing one of the previously described conditions. For example, if it is unknown whether a patient or subject is allergic to a particular drug, the amide compound, combinations of amide compounds, or compositions thereof, can be administered prior to administration of the drug to avoid or ameliorate an allergic response to the drug. Alternatively, prophylactic administration can be used to avoid or ameliorate the onset of symptoms in a patient diagnosed with the underlying disorder. For example, an amide compound(s), or composition thereof, can be administered to an allergy sufferer prior to expected exposure to the allergen. An amide compound, combinations of amide compounds, or compositions thereof, can also be administered prophylactically to healthy individuals who are repeatedly exposed to agents known to one of the above- described maladies to prevent the onset of the disorder. For example, an amide compound, combinations of amide compounds, or compositions thereof, can be administered to a healthy individual who is repeatedly exposed to an allergen known to induce allergies, such as latex, in an effort to prevent the individual from developing an allergy. Alternatively, an amide compound, combinations of amide compounds, or compositions thereof, can be administered to a patient suffering from asthma prior to partaking in activities which trigger asthma attacks to lessen the severity of, or avoid altogether, an asthmatic episode.

Effective dosages can be estimated initially from in vitro assays. For example, an initial dosage for use in subjects can be formulated to achieve a circulating blood or serum concentration of active compound that is at or above an IC ₅₀ or EC 50 of the particular compound as measured in an in vitro assay. Dosages can be calculated to achieve such circulating blood or serum concentrations taking into account the

bioavailability of the particular compound. Fingl & Woodbury, "General Principles," In: Goodman and Gilman's The Pharmaceutical Basis of Therapeutics, Chapter 1, pages 1-46, Pergamon Press, and the references cited therein, provide additional guidance concerning effective dosages.

In some embodiments, the disclosed compounds have an EC 50 from greater than 0 to 20 μΜ, such as from greater than 0 to 10 μΜ, from greater than 0 to 5 μΜ, from greater than 0 to 1 μΜ, from greater than 0 to 0.5 μΜ, from greater than 0 to 0.1 μΜ, or from greater than 0 to 0.05 μΜ.

Initial dosages can also be estimated from in vivo data, such as animal models. Animal models useful for testing the efficacy of compounds to treat or prevent the various diseases described above are well-known in the art. Suitable animal models of hypersensitivity or allergic reactions are described in Foster, (1995) Allergy 50(21Suppl):6-9, discussion 34-38 and Tumas et al, (2001), J. Allergy Clin.

Immunol. 107(6): 1025-1033. Suitable animal models of allergic rhinitis are described in Szelenyi et al., (2000), Arzneimittelforschung 50(11): 1037-42; Kawaguchi et al, (1994), Clin. Exp. Allergy 24(3):238-244 and Sugimoto et al, (2000), Immunopharmacology 48(1): 1 -7. Persons of ordinary skill in the art can adapt such information to determine dosages suitable for human administration.

Dosage amounts of disclosed amide compounds will typically be in the range of from about greater than 0 mg/kg/day, such as 0.0001 mg/kg/day or 0.001 mg/kg/day or 0.01 mg/kg/day, up to at least about 100 mg/kg/day. More typically, the dosage (or effective amount) may range from about 0.0025 mg/kg to about 1 mg/kg administered at least once per day, such as from 0.01 mg/kg to about 0.5 mg/kg or from about 0.05 mg/kg to about 0.15 mg/kg. The total daily dosage typically ranges from about 0.1 mg/kg to about 5 mg/kg or to about 20 mg/kg per day, such as from 0.5 mg/kg to about 10 mg/kg per day or from about 0.7 mg/kg per day to about 2.5 mg/kg/day. Dosage amounts can be higher or lower depending upon, among other factors, the activity of the amide compound, its bioavailability, the mode of administration, and various factors discussed above.

Dosage amount and dosage interval can be adjusted for individuals to provide plasma levels of the amide compound that are sufficient to maintain therapeutic or prophylactic effect. For example, the compounds can be administered once per day, multiple times per day, once per week, multiple times per week (e.g., every other day), one per month, multiple times per month, or once per year, depending upon, amongst other things, the mode of administration, the specific indication being treated, and the judgment of the prescribing physician. Persons of ordinary skill in the art will be able to optimize effective local dosages without undue experimentation.

Compositions comprising one or more of the disclosed amide compounds typically comprise from greater than 0 up to 99% of the amide compound, or compounds, and/or other therapeutic agent by total weight percent. More typically, compositions comprising one or more of the disclosed amide compounds comprise from about 1 to about 20 total weight percent of the amide compound and other therapeutic agent, and from about 80 to about 99 weight percent of a pharmaceutically acceptable additive.

Preferably, the amide compound, combinations of amide compounds, or compositions thereof, will provide therapeutic or prophylactic benefit without causing substantial toxicity. Toxicity of the amide compound can be determined using standard pharmaceutical procedures. The dose ratio between toxic and therapeutic (or prophylactic) effect is the therapeutic index. Amide compounds that exhibit high therapeutic indices are preferred.

Human PBMC cells (400 million) obtained from the vendor were transferred into a T-175 flask containing 15 ml RPMI media (10% FBS) and incubate for 2 hours at 37 °C. After 2 hours, the media including floating cells was aspirated out carefully and 12 ml of fresh RPMI media (10% FBS) containing GMCSF (100 ng/ml) and IL4 (20 ng/ml) was added, and the flask was kept in a 37 °C incubator for 7 days.

After 3 days, fresh GMCSF (100 ng/ml) and IL4 (20 ng/ml) were added to the flask and the incubation continued. After 7 days, the fully differentiated cells were harvested by spinning down (1200 rpm / 5 min) and aspirating the media. The cells were suspended in fresh RPMI media (10% FBS) containing 50ng/ml IFNy (1000 U/ml) and then plated (50K/well in 100 μΐ) onto a white clear bottom 96 well plate and left in a 37 °C incubator for 24 hours.

II. Addition of compounds:

After 24 hours incubation, 100 μΐ of RPMI media was added containing 2X concentrated test compound per well to the above cell-culture media (final concentration becomes IX) and the plates were pre-incubated for 1 hour at 37 °C before stimulating with LPS.

After 1 hour compound pre-incubation, 10 μΐ per well of 20X concentrated LPS solution in RPMI media was added to give a final concentration of 1 μg/ml. The mixture was shaken and incubated the plates at 37 °C for an additional 18 hours.

155 μΐ of the supernatant was harvested from each well carefully (without the tip touching the bottom of the well) and to the remaining 50 μΐ / well of the cell culture plate was added 50 μΐ of Cell Titer Glo reagent. The mixture was incubated for 1-2 minutes on a shaker and the plate was read for luminescence intensity to determine the compound cytotoxicity. The cell culture supernatant collected above was used to carry out IL23 ELISA (65 μΐ -Supernatant) and IL10 ELISA (90 μΐ - Supernatant) as described below. Example 125
